Question

Rani took a wire of length 44 cm and bent it into the shape of a circle. Find the radius of that circle. Also find its area. If the same wire is bent into shape of a square, what will be the length of each of its sides? Which figure encloses more area, the circle or the square? (Take

=22/7)​

Answer 1

Answer:

radius = 7

area of circle = 154 cm²

length of side of square = 11cm

area of square= 121 cm²

circle encloses more area then the square

Step-by-step explanation:

circumference of circle is 44 cm because the length of the wire is 44cm.

circumference = 2 π r

44 = 2 ×22/7 ×r

r = 44//2 × 7/22

r = 22 × 7/22

r = 7

area of circle= π r²

area = 22/7 × 7²

area = 22×7

area = 154 cm²

perimeter of square = 44

all sides of square are equal so 4x = 44

x = 11

each side of square measure 11 cm

area of square = side ²

= 11²

area of square = 121 cm²
